10 Best Backpack Coolers 2026 in the United States

The YETI Hopper M12 Backpack Soft Cooler is a solid choice for campers and hikers needing a reliable way to keep drinks and small food items cold on the go. It can hold up to 240 fluid ounces, roughly the size needed for about 20 cans, which is handy for day trips or small gatherings. Its ColdCell insulation uses closed-cell foam that does a great job maintaining chill for hours, so your beverages stay refreshingly cold. The DryHide shell is made from tough, puncture-resistant vinyl that also protects against sun damage, making it durable enough for outdoor adventures.

One standout feature is the MagShield Access - strong magnets form a leak-resistant seal while allowing easy access to your items, which helps prevent spills but keeps the cooler securely closed when needed. The backpack design includes comfortable multiple carry handles and a practical kangaroo pocket outside for small essentials like keys or a phone. However, at around 3 kilograms (6.7 pounds), it might feel a bit heavy when fully packed, especially if you’re hiking long distances. Also, while it is leakproof, users should still handle it carefully to avoid messes.

Its size is perfect for personal use or small groups but might be limiting if you want to carry larger quantities or bigger items. The YETI Hopper M12 Backpack offers excellent insulation, durability, and smart features that suit outdoor enthusiasts looking for a dependable cooler backpack that balances comfort with tough materials.

The Stanley All Day Julienne Mini Soft Cooler Bag is a compact yet effective choice for anyone looking to keep their food and drinks cool during outings. With a capacity to hold up to 10 cans or 7.2 quarts, it’s perfect for picnics, beach days, or hikes. The insulation can keep items chilled for approximately 12 hours, which is quite decent for a soft cooler of its size. The unique 'doctor's bag' design allows for easy access and adds a touch of style, making it suitable for both men and women. Additionally, the cooler features a durable construction with a sturdy zipper and snap-top handles, ensuring it can handle regular use without showing wear and tear quickly. The detachable shoulder strap adds to its portability, catering to users who prefer hands-free carrying.

There are a few things to consider. While the 12-hour cooling capability is good, it may not be sufficient for all-day outdoor adventures if you’re planning to keep items cold for longer than that. The size may also limit its use for larger groups or longer trips where more capacity might be needed. Some users may find the weight of 1.19 pounds slightly on the heavier side when fully loaded, especially during long hikes. Lastly, while it boasts a lifetime warranty, some users may be cautious about how well it holds up over time in various conditions.

The Stanley All Day Julienne Mini Cooler is an excellent option for casual day trips and small gatherings. Those needing extended cooling or larger capacity may want to explore other options. It's stylish, practical, and built for life, but it's essential to align your needs with its specifications.

The Hydro Flask Cooler Backpack offers a solid 20-liter capacity, enough to hold about 38 cans, making it a great choice for beach trips, travel, or outdoor activities like camping and hiking. Its insulation keeps contents cold for up to 24 hours when combined with ice packs, which is impressive for a soft cooler in this size range. Weighing just 2.49 pounds, it’s relatively lightweight, and while it includes a removable cross-body strap for carrying, it does not have padded shoulder straps like a traditional backpack, which could influence comfort on longer walks.

Made from 100% recycled polyester with a water-resistant coating, the cooler provides good durability and protection from light moisture. The compression-molded lid and base help maintain its shape. Its large, zippered top allows easy access and cleaning, and the leakproof lining prevents spills from soaking through. This cooler backpack is ideal for those seeking reliable insulation and durability in a simple, easy-to-carry design, though it may not be the best choice for those needing multiple compartments or maximum carrying comfort for extended hikes.
